ABEL H. FROST, OF CHICAGO, ILLINOIS.

BUCKLE.

SPECIFICATION forming part of Letters Patent No. 249,829, dated November22, 1881.

Application led January 15, 1881.

To all whom it may concern Beit known that I, ABEL H. Faos'r, ofChicago, State of Illinois, have invented certain new and usefulImprovements in Buckles; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to the vclass of buckles which have the tonguehinged to an end bar of the frame and the free end of the tonguesupported centrally as to the frame. It is more especially animprovement on the buckle patented to W. T. Beaser in Letters Patent No.176,053, dated April 1l, 1876, wherein the free end of the tongue isshown anddescribed as resting on the central stud, E. ln practical useof the buckle mentioned it is found to be dilticult to keep the tongueon the studthat is to say, itslips od' to one side. This gives a bad'appearance to the buckle and throws the strain sidewise upon thetongue, with danger of its drawing through. I have remedied this faultby making the tongue of such shorter length as to clear the studentirely, thereby allowing said tongue to rest on an underlying fold ofthe strap or straps. I have also broadened the central depressedcross-bar upon which the stud is formed, so as to support the leatherbeneath the free end of the tongue.

In the drawings, Figure 1 is a central longitudinal section of a singlestrap and buckle through cc x ot Fig. 2; and Fig. 2 is a topview of thebuckle and strap.

The same letter indicates the same part in both figures.

II H are the side bars, and B and C are the end bars, of thebuckle-frame.

D is the depressed central cross-bar, and E a stud projecting upwardfrom the middle of said cross-bar D. n

A is the tongue, hingedto the end bar B. Said tongue A is made of such`length as to fairly clear the stud E when dropped down within the frame.The strap or straps F being inserted in the manner contemplated in this(No model.)

.wardly past the cross-bar D, said cross-bar is extended on the sidetoward the tongue, to support the leather beneath the point on which-.the freeend ot' the tongue bears, as seen in Fig. 1, and as indicatedby dotted linesin Fig. 2.

A secondary7 but material advantage of the construction shown is foundin the fact that the tongue, arranged to rest on a fold of the leather,instead of resting upon the stud, serves to hold the lower fold or foldsof the strap snugly down to the cross-bar, or about the base of thenecessarily tapering stud, whereby the full strength of the stud is madeavailable and all parts lie more closely together. By curving the tongueto bear broadly upon the strap, as shown in Fig. 1, said strap beingsupported by the cross-bar D in the manner described, strain upon thebuckle does not materially tend to draw the tongue into the surface uponwhich it rests.

While the cross-bar D is shown in Fig..2 as having a curved edge, or asbeing made broad, for the purpose stated only in its central portion, itmay obviously be ot' equal breadth throughout its length.

I claim as my invention- In the buckle described, having the centraldepressed cross-bar,D,provided with the stud E, the tongue A, hinged tothe end bar B, and made of such length as to clear the stud, and theeross-barD extended to give support to the leather beneath the end ofthe tongue, substantially as described, and for the purposes set forth.

In testimony that I claim the foregoing as my invention I affix mysignature in presence of two witnesses.
